  Rune particle system (Message 1 to 3 of 3)

I am having problems with Rune's particle system. The particle macros 
use the clock in the chronological sense of passing time, whereas I am 
using the clock simply to rotate the camera and want time to stand 
still. This obviously produces a conflict.

My question is, how do I "freeze" the particles so that they don't 
change as the clock value increases? I've tried changing the 
"particle_start" and "particle_end" parameters so that they are equal, 
but this causes the particles to not appear at all. Is there a way to 
override the clock?

Thanks.

  If nothing else works, you could go and replace all instances of 'clock'
with eg. 'PSClock' and then add this to the beginning of the include:

#ifndef(PSClock)
  #define PSClock = clock;
#end

  Then you can override PSClock with your own value from the outside.

Thanks. It ended up being because I didn't read the docs properly. You 
can set the clock value in the INI settings.
